This study developed a 2×4 dual-band left-handed circular polarization (LHCP) patch antenna array for receiving Global Positioning System (GPS) reflections at 1227 MHz and 1575 MHz. The antenna element is achieved by probe feed stacked patch and the signal is combined by an 8-way power divider. According to the measured results, the axial ratio at the center frequencies is below 3 dB and the peak...
